4 Claims.

1 This Iinvention relates to chiropractic equipment, or supportingdevices for the human body and its appurtenances during theIadministration of chiropractic adjustments, and it has particularreference to an automatic chiropractic table by the use of whichanatomical adjustments can be performed by persons skilled in thescience conventionally designated as chiropractics, and its principalobject resides in the provision of an adjusting table in which isembodied a multiplicity of unique features by which the operator caneffect the proper arrangement of the body, by the manipulation ofcertain adjusting devices, whereby to perform the necessary or desiredadjustments along the spinal column of the patient, or to effect therelaxation of muscular tension, and other functions of the science,which can best be performed when the subject or patient is in suchreclined and relaxed position.

Another object of the invention resides in the provision of achiropractic adjusting table which is capable of both vertical andhorizontal positions, conventionally referred to professionally as ahylo table, operated by an electric motor and comprising a compact andsimple structure requiring a relatively small space for its use andoperation, yet providing adequate facilities in the performance of thefunctions of one skilled in the art of chiropractic science, theinvention possessing such salient features of construction as to renderit capable of true vertical and horizontal positioning, as well asvariable positions between the vertical and horizontal, if desirable,thus affording an effective medium by which chiropractic patients can behandled easily and with a minimum of effort yet with the leastinconvenience to the subject,

A still further object of the invention resides in the provision ofindependently adjustable bodysupporting cushions arranged along thetable and capable of being positioned in such a manner as to properlysupport the patient in' relaxed position and to contact portions of thebody while affording the patient the maximum of comfort during theadministration of the chiropractic treatments, the said adjustmentsbeing so arranged as to be capableof performance while the patient isreclining upon the table, and which adjustments may be found desirableafter the patient has assumed his or her position thereon.

Broadly, the invention contemplates the provision of an automaticallyadjustable table, for use in the application vof chiropractic science,

which is simple and' compact in design and economical in construction,as well as attractive in appearance, and seeks to afford a mediumwhereby chiropractic adjustments can be performed with greater ease andefficiency than is found conventionally possible with equipmentcurrently available to practitioners of the science.

While the foregoing objects are paramount, other and lesser objects willbecome manifest as the description proceeds, taken in connection withthe appended drawings, wherein:

Figure 12 is a plan view of the invention when arranged in horizontalposition, shown in Figure illustrating the adjusted positions of thesupporting cushion in dotted lines.

Figure 13 is a side elevational view of the invention arranged inhorizontal or operative position, and

Figure lll is a side elevational View of the invention showing same invertical or inoperative position.

The invention accordingly comprises a base i which has vertical flanges2 providing a partial housing for a motor 3 supported on the base i foroperating the invention in a manner which will be presently described.The flanges 2 have vertically extended members ii which function asbearing supports for the stationary axis cr pivot 5 upon which a frame Sis mounted.

The axis 5 is arranged transversely through the frame 5 and is spacedfrom one end to permit the frame to assume the vertical position shownin Figure 14. The frame 6 embraces all of the operative parts of theinvention, as manifest in Figures 1 to G, inclusive, and is enclosed bya housing '5. The enclosed assembly will be hereafter referred to as atable 8 for clarity.

The table 8 is operated from horizontal to vertical positions, shown inFigures 13 and 14, and contrariwise, by the motor 3 through arms 9,keyed to the ends of stub shafts I of the gear reduction boxes I I, andconnecting links I2 which are hingedly secured by pins I3 to the outerends of the arms S, the opposite ends of the links i2 being pivoted on ashaft I4 extending across the back of the table 8, as shown in Figure 1.

rEhe arms il have opposing counter-weights l affording smootheroperation of the assembly.

rlhe motor 3 is preferably arranged on the base i so that its shaft isparallel to the longitudinal axis of the table 8 and, through a suitableworm and gear assembly arranged in a housing it, rotates the shafts I0through the gear reduction assemblies I I. It is expedient to providethe latter to accomplish the relatively slow movement of the table 8, inoperation, which is desirable.

The supporting members for the patients body are arranged upon carriagesslidably supported in the frame G on the front of the table S so thatthe carriages can be adjusted relative to each other longitudinally ofthe table 8.

The carriage Il, forwardly of the table S supports the head-rest membersIS and IS', the chest support I9, and the abdominal support 2S, whilethe carriage 2|, rearwardly of the table 8, carries the thigh orlower-body support 22, as illustrated in Figure 1.

The carriage Il, a front end view of Which is shown in Figure 4, and atransverse sectional view being illustrated in Figure 7, comprises aframe 23 which is rectangular in shape and has integral ribs 24 formedalong each side adapted to be slidably arranged in grooves 25 definedbetween spaced bars 2S secured longitudinally along the inner side Wallsofk the housing 1, as apparent in Figures 4 and 7, and by which theassembly is supportedin the frame E.

The carriage frame 23, the rectangular form of which is shown in Figure9, has a horizontally arranged partition 2I forming an open housing 28therebeneath in which a part of the adjusting mechanism for theabdominal support 2i! is enclosed and which Will be described presently.Vertical standards 29 are integrally formed with the frame 23 and extendupwardly therefrom on each side providing spaced supports for the pairedsections l5 and I8 of the head rest, and the adjusting mechanismtherefor, as shown in Figures '7 and 8.

The carriage Il is moved longitudinally of the frame 6 by the manualrotation of a shaft 33 -arranged transversely of the frame 23 andjournalled in each of the standards 29 and having a pinion 3| at eachend engageable with rack bars 32 secured to the inner side walls of thehousing 'I and arranged longitudinally thereof, as apparent in Figuresl, 3, 4 and 7. One end of the shaft 3S extends through a slot S3 in awall of the housing 'l and is adapted to move therealong as it ismanually rotated by a crank 34 attached to its extended end, as shown inFigures 3, l and 13.

The head rest IB-I8 is adjustable to cause the paired sectionsl to moveyrelative to veach other in opposite directions laterally and provide agap or space therebetween of variable proportions. As Will becomemanifest, the patient, when occupying the table, is properly lying facedown, the sides of his face bearing upon the opposing sides of thecushioned members iii-I8' while his face is extended into the spacetherebetween.

The spacing adjustment of `the members Iii-I8 is accomplished :by therotation of la rightand left-handthreaded rod or shaft 35 arranged inthreaded bores through integral flanges'S formed on the bottom of eachof the members IS-IB', as vapparent in Figures 4, 7 and'8, and'rotatable by a crank 3'! on one end. The members Ill-I8 move inopposite directions, sliding along a polygonal shaft 33 which is`arranged through polygonal apertures through the flanges 36 of the headrest members I-IS, and journalled forrotation at each end in the upperends of the 'standards 29. The shaft 38 thus actually supports themembers i8-I8 and provides a limited rotative adjustment therefor topermit the same to be tilted forwardly to various positions as desiredto effect the desired positions of the patients head,

At each end of the shaft 38 is a jaw coupling, each comprising, in part,a stationary disk-like member 40, rigidly secured by rivets a, or thelike, to the upper-end of each of the standards 29 and providingbearings for the ends of the shaft 38. The opposing inner faces of themembers 40 are formed with radial serrations having their inclinationsin one direction to permit a rotative ratchet action of the companionmembers 4I whose operative faces are formed with complementary radialserrations and have polygonal axial bores adapting them to slidablemountings on the shaft 38. Each of the members 4I are formed withintegral flanges 2 spaced from the members 4I to denelgrooves 43 toaccommodate disengaging forks 44 and 45, the former being integral witha polygonal plunger 46 arranged through polygonal apertures in theflanges 36 and parallel to the shafts 35 and 36, previously described.

The opposite fork is hingedly connected to the end of a link 41 whoseopposite end is pivoted to a bell crank 48 having a toggle associationwith the-plunger 45. The bell crank 48 is pivoted, at its bend, to aplate 49 arranged on the shaft 38 intermediate the flanges 36 and isyieldably retained by coil springs 50 on each side,

bearing at their opposite ends, against the iianges 36, as apparent inFigures 4, 7 and 8. Thus, to raise the forward ends of the head-restmembers I 8-I8 it is necessary only to raise them to the desiredposition against the ratchet action of the jaw couplings, the members 4Ibeing tensioned by coil springs 5l arranged about the shaft 33 andbearing against stationary washers 52 thereon, and thus are yieldablewith respect to the stationary jaw members 4).

In order to lower the forward ends of the members l8-|8, however, theplunger 46 must be urged inwardly, by pressure upon the head 53 thereof,to move the sliding jaw members 4l away from their companion stationarymembers 40 against the tension of the springs 5I while pressure isapplied to the head support members I8--I8 to lower them to the desiredposition. Obviously, the operation of the plunger 46 inwardly willactuate the forks 44 and 45 by the bell crank and linkage assemblypreviously described.

The chest support I9 is mounted on a rod 54 arranged transversely of thetable 8 and through brackets 55 secured to the underside of the supporti9, as apparent in Figures l, 13 and le. The ends of the rod 54 areconnected to the upper ends of standards 56 positioned at an angledownwardly and forwardly of the as sembly, their lower ends extendinginto welk 51 formed in supporting blocks 58 rigidly secured to the innersides of the standards 25, as shown in Figures 1 and 7, and inclined sothat the standards 56 have a sliding, pistonlike action therein againstsprings 5S' in the bottoms of the wells 51. A cushioning action of thechest support I9 is the result of the mounting arrangement justdescribed.

Rearwardly of the chest support I5 is an abdominal support which has itsbearing on the ends of rearwardly projecting arms 59 whose forward endshave sections 60 of a pair of jaw couplings rigidly attached thereto.The members Eil are similar to the disk-like members 4@ or 4|, of thehead support assembly, and have their engaging faces formed with radialserrations whose inclinations are in one direction, as apparent inFigures 10` and l1.

The members 65 are axially bored and threaded, rightand left-hand, andare threadedly applied to a shaft 5| whose ends are journalled in ears62 formed on the standards 29, as in Figures 1 and 10. A knurled knob B3is provided on one end of the shaft 5l for rotating the same and isshown in Figure 4. By turning the knob 63 the members 65 are movedtoward each other so that their serrated faces will become disengagedfrom the corresponding radially serrated faces of complementary members@il rigidly secured to the upper ends of spaced arms which extenddownwardly, with slight outward offset bends b, and are connected attheir opposite ends with a rod 66 extending therebetween.

in Figure 91 is illustrated, in plan, a tensioning or holding assemblyfor the abdominal support 2i) whereby the same can be properly tensionedwhen the desired adjustment is accomplished. In the assembly there are aplurality of spaced and parallel arranged rods 61 whose free ends extendthrough vertical slots B8, in the depending ange 59 of the open housing28 in the bottom of the frame 23, and turn downwardly forming hooks ,15which are adapted to se- 6 lectively overreach and restrain the rod 66in the manner shown in Figures 4 and 10.

All of the rods 61 normally lie across a plurality of spaced bars 1|which are slidably supported in guides 12 and 13 on each side of theframe 23, as illustrated in Figure 9, and each of the bars 1| is formedwith a vertical lever 14, on the right side of the table 8, as onestands behind the head rests, by which they can be longitudinallyoperated in the guides 12 and 13 by plungers 15 extending through theslot 33 in the wall of the housing 1.

Each bar 1l has a cam 16 formed on its upper edge capable of engagingone of the rods B1, when each is moved longitudinally, to raise the sameand free the rod 66. It is contemplated, however, that the bars 1I willbe positioned, in operation, so that all but one of the rods 61 are inraised position and thus only one being engaged with the rod 65, as inFigures 4 and 7.

Each rod 61 is hingedly connected, at its opposite end, with plungerrods 11 having clevises 18 thereon and operatively arranged throughsleeves 19 in the rear member of the frame 23. All except one of therods 61 are slidably arranged in the sleeves 19 and have compressionsprings arranged thereon so that a tension is exerted when pressure isapplied to the abdominal support 25.

The single rod 51 having no spring 85 is rigidly secured in the frame 23by a nut 8l and, when it engages the rod 66 the abdomen support 20 isalso rigid and unyielding. Each of the springs 8D can be adjusted toincrease or decrease tension by nuts 82 threaded on the ends of theplunger rods 11. The abdominal support 20 may be capable of a limiteddownward movement, as indicated in dotted lines in Figure 1, whenpressure is applied thereto, due to the cushioning action of the springsEll. Higher adjustment of the member 25 may be accomplished by simplyraising up on the same against the ratchet action of the members eil-54,the outward tension of the arms 59, which flex inwardly, serving toretain the members 65--54 in engagement to normally hold the arms 59 inrigid association with the arms S5, as in Figure 10.

The carriage 2l, on which the support 22 is mounted, comprises a plate83 which has a depending iiange 84 in front to which is pivotallyconnected a bar 85 which extends forwardly of the table 8 and is formedwith a series of serrations or notches 86 toward its free end, theinclinations of which are directed forwardly, as in Figure 1, the saidnotches 8S being engageable by a cam, or movable stop 81 which isslidably operated transversely of the table 8 by a plunger 88 extendingthrough the slot 33 on the left side of the table, as shown in Figures3, 4, 7 and 13. The stop B1 is formed with an angular surface c whichengages the bar 85 and obviously expedites the movement of the stop 81.The plunger 88 is formed with the stop 31 by a vertically arrangedintegral arm 85. The bar 85 operates in a guide member 95 risingvertically from the frame 23.

The carriage 2l is moved longitudinally of the table 8 by a rack bar 9|which has a round threaded portion 52 upon which is threaded a bevelledpinion 93 rotatably secured to an L- shaped bracket 94 which ispivotally connected to the bearing hanger casting 95, illustrated inperspective in Figure 2, and shown in Figures l,

3 and 5. The casting is substantially U'-shaped and has a shaft 36journalled. through its upwardly projecting legs 91 and arrangedtransversely of the table 8;

Near one -end of the shaft 9'6 is a pinion 98 thereon which is meshedwith another pinion 93 therebeneath on the' end of a worm |00 having itsbearings in the legs 9.1 of. the casting. 95; and opposite the pinion99', extends through the L- shaped bracket 34, by which the latter is.pivotally supported, and has a bevelled :pinion IG! thereon meshingwith the pinion 93;

The worm le is in mesh with a` worm gear 1%"2 on a transverse axis inthe lower portion |03 of the casting 95 and has. a polygonal shaft |04slidably arranged through its polygonala'xial bore whereby, when eitherof the cranks or IDB on each end of the shaft 85' is turned, thejpolygonal shaft |=l is rotatedand. by reason ofthe rotation of thepinion S3 which is threadedly associated with the threaded portion 32 ofthe rack barSI, the carriage 2| is moved forward, the teeth |01 of thebar 9| being en'gageable by a depending flange |88 on the rear of thecarriage 2|, as illustrated in Figure 1.

The shaft |24 is rotatably journalled near one end in a hanger Itattached tothe flange 84 in front of the carriage 2| and has' a crank orcam H0 on its extremity which, when' rotated, engages the horizontalmember of the substantially U-shaped frame member ||2 supporting thecushion 22 andraises" the latter, according to the degree of rotation,in the manner shown in dotted lines in Figure l.

The fra-me 2| is slidably supportedin the housing 'i on bars H3 byflanges ||4 on each side of the plate S3, shown more in detail in Figure6, by which grooves are dened between their upper edges and the top ofthe housing The teeth |31 of the bar 9| do not engage the flange member|68, however, until the bar 9| is raised by the cam I i9 when the latterengages the-horizontal member the spring. ||5, shownn Figure 1,providing a yieldable connection between the bar 9| and the framemember2`.

By turning either of the cranksA |55* or |06 the frame 2| canhbemoved-upwardA in front' and forward, as indicated in dotted lines inFigure 1, and thus prevent dragging the fore' part of the patients bodybackwards when itis desirable to raise or adjust the position o'f. theYlower part of the body.

The longitudinal movement ofthe carriages and 2| with respect to eachother is accomplished by the operation of the crank 34 operating: thepinions 3| along the rack bars 32;.an adjustable connection between thecarriages IT andA 2| being had through the notched bar 85. When thecarriages are connected by the bar 85, however, both move forwardly onthe table 8 in the same manner. The dotted lines in Figure 12 indicatethe variable relationship that can be accomplished by the adjustmentsdescribed.

A bumper spring H6 is secured to the b'ac'kof the flange |68 on therearl of the carriage 2| to absorb the shock when the latterisrelea'sedlwhile the table 8 is in a verticalposition. The. spring IISis designed to strike against a stop secured to the underside of the topofv the housing 1.

The rear portion of the cushion 2-2Y is. supported on a pair ofstandards ||8 and is-pivoted to their upper ends. These standards arerigidly secured to the plate S3 and, like the front members ||2, operatein slots ||9 in the top anaal-ong each side of the-table S. The cushion22 is alsopi'v` otally attached to thev upper endsof the" standardsl l2;y Y Y A-tread stand |207` isv attached to the rear end of the table 8-and is adapted to assume a horizontal position, transverse to thelongitudinal planeof the table 8 when the latter is in vertical'position, shown in Figure 14. As the table 8 assumes the horizontalposition-shown in Figure 13, however, the stand |251 is moved to anangular positionof about 45degrees.

rlhe stand is attached to a shaft lf2-i across the rear of the table S,as shown in Figures l and 3, tol which is securedi al lever |22? havinga link |23 pivoted thereto and connected, at its opposite end, toanother lever |211V on the main axial shaft 5 which, as previouslystated, i's stationary. The movement of thc table 8 will automaticallyadjust the stand |20 to its desired positions. Y

A supporting leg or apron |25 is arranged on the forward end of thetable 8 and' is pivoted on the ends of a shaft |26 arranged transverselythrough the bottom of the housing as shown Figures 1 and fl, adaptingthe apron |25 to assume a vertical position to support the front end ofthe table il in its horizontal position. The shaft |25 has a lever |21xed rigidly thereon to which is pivotally connected a rod |23 whichextends rearwardly through the housing and is pivotally attached toanother lever |29 on the shaft 5. The member |25 thus is automaticallyraised or lowered, as the table 8 is moved. folding into an opening |30in the bottom-of the f housing l, as depicted in Figure 1.

A leg rest |3|, comprising a cushion supported upon the upper end of aracked standard |32, is arranged on the rear end of the table 8 and isadapted to be adjusted to various heights and automatically raised tooperative position by the action of the table 3. The standard |32 ispreferably arranged on one side ofy the table 3, the cushion |3|extending laterally from its upper end and across the table S.

An' operating mechanism for the rest |3| comprises a shaft |33 arrangedin a bearing |34, supported in the housing and av pinion |33 on theenelV of the shaft |33l meshed with the teeth of the standard |32. Theshaft |33 s'rotated through a clutchl |34 by a shaft |35 supported in abearing |36 and having a bevelled pinion |31, on its opposite end, whichis engaged by a bevelled gear |38 on the axial shaft 5 of the assembly,as shown in Figures 1 and 3.

The clutch is operable by a fork |39 and a rod H38 connected to a bellcrank IM. A lever |42 is connected to the opposite-side of the bellcrank IM and extends through the wall of the housing 'I and has a knob|43thereon. Thus, if it is desirable that the rest |3`| not be raisedwhen the table S is lowered, it is only necessary to disengagc theclutch |34'.

A counter-balance weight U24 is arranged in a slide in the bottom of thehousing 1 and is supported on a chain |45 connected. at its oppositeend, to-the frontcarriage- I1. The chain |45 is operated over a sprocketor pulley |46 secured in the end of the housing 7. The weight |44 servesto counter-balance the weight of the carriages and 2| when the table 8is in a vertical position.

Manifestly, the structure herein shown and described is capable ofconsiderable changes in modicat'ions from time to time, by personsskilled inthe' art, without departing from the spirit of the inventionor the scope of the appended claims.
